The "decent reasons" just sounds like snobbery or a reason to feel superior. Cars are cars, whether manual, automatic, CVT, whatever. Why should bikes be any different?
I'm a big fan of two-wheeled transport in all its forms, but wow is there a prevailing toxic attitude among a large group of "true motorcycle" riders. Instead of welcoming people into the fold, it's just tribalism -- you drive a scooter, you're not a true biker; you ride a cruiser, true bikers only drive super sports; you drive an e-bike, but only loud pipes make a true rider!
Agree about the snobbery, but there is a real difference in kind between them that would be nice to have a good name for. Even if, as the other reply pointed out, they exist on a spectrum, the endpoints are pretty distinct.
